苏联于六十年代后期开始研究高温合金的定向凝固和单晶技术,取得显著成绩,从七十年代中期就大量生产定向凝固叶片,用于航空和地面涡轮。与此同时,研制出一批颇具特色的定向和单晶合金以及相应的工艺。本文拟对苏联近年来有关这方面的资料作简要综述。
The Soviet Union started to study the directional solidification and single crystal technology of superalloys in the late 1960s, notably by mass producing directional solidification blades from the mid-1970s for use in aviation and surface turbines. At the same time, developed a number of distinctive directional and single crystal alloys and the corresponding process. This article is intended to give a brief overview of the Soviet Union in this regard in this regard.
